This is a Tombo Major Boy harmonica. It's a gift, so it's unused, but I'm listing it as near-new. The key is F. There's a sticker on the side. I think the last time I used it was over 10 years ago. I'm selling it because I don't use it anymore. I've only lightly cleaned it with wet wipes, alcohol, and cotton swabs. I haven't checked the operation, but I used it without any problems, so I think it should work normally.
